The elements l3 extend uplower ends and connected together. With the wardly to about the position of the uppermost construction as shown, the principal function of spacers l2 whereupon they bend sharply vupthe beam 29 is to tie the various pairs of trusses 45 wardly as indicated at [4 and terminate in-outtogether, holding them in upright position and wardly turned flanges IS. The angles formed by provide support for the control elements desired the portions l4 and I5 may be regarded as the to be located between the various pairs of trusses. lateral edges of the ventilation opening. By reference to Fig. 5 it will be seen that there Supported on the roof adjacent the edges of is mounted on the I beam II a fabricated Ibeam 50 the ventilation opening are spaced trusses indi- 3| which carries intermediate its ends journals cated generally by the reference character I6. 32 adapted to receive a mounting rod 33 for a These trusses are positioned with their edges preplurality of winding drums 34. The journal elesented toward the opening and lie in vertical ments 32 are mounted at intervals along the I planes perpendicular to the edges of the ventilabeam 2|. Pivoted to the upper flanges 35 of the I 55 beam 3! as by means of suitable hinges 3B are closure elements 31. These elements are adapted to extend from the flanges 35 to overlie the flanges l5 of the roofing element l3. It will be noted by reference to Fig. 2 that the closure elements 31 are arranged in pairs, each pair being in end to end relation with another pair so that the roof opening may be as long as desired while the length of the closure elements is kept to reasonable proportions. It will be noted that the I beams 3| terminate short of the ends of the clo-.

sures 31 and that the winding drums 34 are located between the ends of the I beams 3| and the ends of the closures 31 so that a flexible element may pass between the closure elements.

Attached to the beam 29 is a bracket 38 supporting spaced pulleys 39. At the outer edges of the closures 3'! are lugs 40 to which are attached flexible elements 4i. These elements pass over the pulleys 39 and are connected to a downwardly extending flexible element 42 which in turn passes to the corresponding winding drum 34. It will be apparent from Fig. 2 that there is one winding drum 34 corresponding to each pair of lugs 40 and that a winding drum and pair of lugs is positioned adjacent the end of each pair of closures. The units are complete and independent except that the rod 33 which carries the winding drums extends the full length of the opening whereby to provide a single control for as many pairs of closures as are necessary to close the ventilation p ning.

The rod 33 is operated by a remote control device shown in Fig. 4. This device includes a housing 43 mounted on the I beam I i and secured thereto, both to the upper flange I I thereof and by means of a brace 44 to a lower portion thereof. The housing 43 embraces journd. means for the rod 33 and for a shaft 45 extending transversely of the rod 33. Mounted on the rod 33 within the housing 43 is a worm gear 46 which meshes with a worm 41 carried by the shaft 45. Secured to the outer end of the shaft 45 is a pulley 48 over which may be trained an endless belt extending downwardly to a position to be accessible to an operator.

While I have shown and described the present preferred embodiment of my invention I wish it understood that the same may be realized in different forms and that I am limited only in accordance with the appended claims.

Having thus described my invention, what I claim is:

1. In combination with a roof having an open ing therein, trusses at each side of said opening and spaced therealong, said trusses extending upwardly and inwardly whereby to have a portion overlying said opening, means securing the trusses at one side of said opening to those at the other side thereof, a ridge roll having terminal edge portions extending along the upper portion of the inner edges of said trusses, said ridge roll overlying and extending laterally beyond said opening, baflle walls covering the outer edges of said trusses and terminating above said roof, damper means adapted to close said opening and comprising a pair of closures, each being pivoted about an axis extending longitudinally of said opening, and means for operating said closures.

2. In combination with a roof having an opening therein, trusses at each side of said opening and spaced therealong, said trusses extending upwardly and inwardly whereby to have a portion overlying said opening, means securing the trusses at one side of said opening to those at the other side thereof, a ridge roll having terminal edge portions extending along the upper portion of the inner edges of said trusses, said ridge roll overlying and extending laterally beyond said opening, baille walls covering the outer edges of said trusses and terminating above said roof, damper means adapted to close said opening and comprising a pair of closures pivoted about an axis extending longitudinally of said opening, and means for operating said closures, said last means comprising pulley means above said damper means, flexible elements secured to said closures in spaced relation to the pivots thereof and extending over said pulley means and downwardly, a winding drum operatively associated with said flexible elements, a worm gear rotatable with said winding drum, a worm meshing with said worm gear and remote control means for operating said worm.

3. In combination with a roof having an opening therein, trusses at each side of said opening and spaced therealong, said trusses extending upupwardly and inwardly whereby to have a portion overlying said opening, means securing the trusses at one side of said opening to those at the other side thereof, a ridge roll having terminal edge portions extending along the upper portion of the inner edges of said trusses, said ridge roll overlying and extending laterally beyond said opening, baille walls covering the outer edges of said trusses and terminating above said roof, damper means adapted to close said opening and comprising a plurality of pairs of closures pivoted about axes extending longitudinally of said opening, each pair being arranged in end to end relation to another pair, and means for operating said closures, said last means comprising a rotatable rod parallel to the axes of said closures and carrying a winding drum for each pair of closures, means including a flexible element for connecting said closures to said winding drums for operation thereby, and remote control means for operating said rod.

4. In combination with a roof having an opening therein, trussesat each side of said opening and spaced therealong, said trusses extending upwardly and inwardly whereby to have a portion overlying said opening, means securing the trusses at one side of said opening to those at the other side thereof, a ridge roll having terminal edge portions extending along the upper portion of the inner edges of said trusses, said ridge roll overlying and extending laterally beyond said opening, baflie walls covering the outer edges of said trusses and terminating above said roof, damper means adapted to close said opening and means for operating said damper means.
